Why Icelanders became bankers, or: a machine for turning cod into PhDs.

What went on before: fishing highlights the tragedy of the commons. Since there is no incentive for fishermen to limit the amount of fish they catch, they tend to catch too many. The supply does not have the time to restock, and the price of fish is low because everybody is selling fish. The classic solution is to turn common property into private property, so that every owner suddenly has an interest.

This insight is what led Iceland to go from being one of the poorest countries in Europe circa 1900 to being one of the richest circa 2000. Iceland’s big change began in the early 1970s, after a couple of years when the fish catch was terrible. The best fishermen returned for a second year in a row without their usual haul of cod and haddock, so the Icelandic government took radical action: they privatized the fish. Each fisherman was assigned a quota, based roughly on his historical catches. If you were a big-time Icelandic fisherman you got this piece of paper that entitled you to, say, 1 percent of the total catch allowed to be pulled from Iceland’s waters that season. Before each season the scientists at the Marine Research Institute would determine the total number of cod or haddock that could be caught without damaging the long-term health of the fish population; from year to year, the numbers of fish you could catch changed. But your percentage of the annual haul was fixed, and this piece of paper entitled you to it in perpetuity.

Even better, if you didn’t want to fish you could sell your quota to someone who did. The quotas thus drifted into the hands of the people to whom they were of the greatest value, the best fishermen, who could extract the fish from the sea with maximum efficiency. You could also take your quota to the bank and borrow against it, and the bank had no trouble assigning a dollar value to your share of the cod pulled, without competition, from the richest cod-fishing grounds on earth. The fish had not only been privatized, they had been securitized.

It was horribly unfair: a public resource—all the fish in the Icelandic sea—was simply turned over to a handful of lucky Icelanders. Overnight, Iceland had its first billionaires, and they were all fishermen. But as social policy it was ingenious: in a single stroke the fish became a source of real, sustainable wealth rather than shaky sustenance. Fewer people were spending less effort catching more or less precisely the right number of fish to maximize the long-term value of Iceland’s fishing grounds. The new wealth transformed Icelandâ€”and turned it from the backwater it had been for 1,100 years to the place that spawned BjÃ¶rk. If Iceland has become famous for its musicians it’s because Icelanders now have time to play music, and much else. Iceland’s youth are paid to study abroad, for instance, and encouraged to cultivate themselves in all sorts of interesting ways. Since its fishing policy transformed Iceland, the place has become, in effect, a machine for turning cod into Ph.D.s.

But this, of course, creates a new problem: people with Ph.D.s don’t want to fish for a living. They need something else to do.
